eufyMake E1 limits that shape a jig
The eufyMake E1 is a desktop UV printer that eufyMake itself encourages using with jigs: its printing tips call them “a lifesaver for batch printing” and recommend a jig whenever you print near the bed edges. Before drawing one, these are the manufacturer limits that decide its size and depth.
| Limit | Value | Source |
|---|---|---|
| Print area (standard flatbed) | 330 x 420 mm (13 x 16.5 in) | eufyMake spec page |
| Max object height recognized by camera | 60 mm | eufyMake E1 FAQ |
| Max printable object height, flatbed | 100 mm | eufyMake E1 FAQ |
| Zero-Point Alignment height | 130 mm (raised from 100 mm) | July 2026 release |
| Max height variation on a single object | 2 mm | eufyMake E1 FAQ |
| Same-height rule | All objects on the platform at the same height | eufyMake E1 FAQ |
| Max printing load | 1.5 kg (3.31 lb) | eufyMake spec page |
| Automatic height adjustment range | plus or minus 0.5 mm | eufyMake spec page |
| 3D texture (emboss) height, flatbed | 5 mm max | eufyMake spec page |
| Camera | 8 MP | eufyMake spec page |
Two of these matter more than they first appear. The same-height rule means every blank in the jig should present its print surface at one height; a jig with uniform pocket depth does that for blanks of one thickness. The 1.5 kg load includes the jig, so heavy blanks hit the weight limit before they run out of bed space.
Rotary printing is an attachment with its own rules: eufyMake’s FAQ requires an object diameter between 40 mm and 100 mm and a perfectly round, straight-sided shape, so spheres such as golf balls go on the flatbed in a jig.
Alignment modes and where a jig helps
The E1 aligns artwork with a snapshot camera plus laser height sensing. eufyMake notes three behaviors that a jig addresses:
- Edge drift. Alignment “can drift as you move toward the edges because of natural lens distortion”; the camera is most accurate at the bed center.
- Height misreads on mats. Snapshot can be off by 1-3 mm when a mat raises the material, and eufyMake recommends Assisted Snapshot to pick the highest point manually. A jig plate behaves like a mat here, so confirm height the same way.
- Raised edges. A lifted tape edge or a magnet sitting at an angle can be read as the highest point and skew the print. Keep the jig flat and magnets seated square.
For batches, Zero-Point Alignment skips camera alignment: you line the material up with the zero point or the bed’s scale marks and set the design to the material’s actual size. eufyMake positions it for edge-to-edge prints on square or rectangular items. The July 2026 release also lists jig batch positioning, described in an image caption as aligning multiple items to fixture holes at once. A jig with a fixed registration corner works with both approaches.
Batch layouts: how many blanks fit
All three layouts below use the same settings so you can compare them: 10 mm plate margin, 4 mm webs between pockets, 0.3 mm clearance per side, on the full 330 x 420 mm area. Usable area is 330 - 20 = 310 mm by 420 - 20 = 400 mm. Each row or column of n pockets needs n x pocket + (n - 1) x 4 mm.
4 in square coasters
- Pocket: 101.6 + 0.6 = 102.2 mm.
- Across 310 mm: 2 pockets use 2 x 102.2 + 4 = 208.4 mm; 3 would need 314.6 mm, which is 4.6 mm too wide.
- Along 400 mm: 3 pockets use 314.6 mm; 4 would need 420.8 mm.
- Result: 2 x 3 = 6 coasters.
Drop the plate margin to 7 mm and the usable width becomes 316 mm, so 3 across fits: 3 x 3 = 9 coasters, 50% more per run. Squares cannot nest in staggered rows, so this margin trade-off is the main lever. Check weight before loading nine ceramic coasters: blanks plus jig must stay under 1.5 kg. Preset: eufyMake E1 4 in coaster jig.
2 in round keychains
- Pocket: 50.8 + 0.6 = 51.4 mm; pitch 55.4 mm.
- Across 310 mm: 5 pockets use 5 x 51.4 + 16 = 273 mm.
- Along 400 mm: 7 pockets use 7 x 51.4 + 24 = 383.8 mm.
- Result: 5 x 7 = 35 keychains in a grid.
Circles nest. Offsetting alternate rows by half a pitch brings the row spacing down to 55.4 x 0.866 = 48.0 mm, which fits 8 rows of 5: 40 keychains. Preset: eufyMake E1 2 in keychain jig.
Golf balls
A conforming golf ball has a diameter of at least 1.680 in (42.67 mm) and weighs no more than 1.620 oz (45.93 g), per the Rules of Equipment.
- Pocket: 42.67 + 0.6 = 43.27 mm; pitch 47.27 mm.
- Grid: 6 across (6 x 43.27 + 20 = 279.6 mm) by 8 down (8 x 43.27 + 28 = 374.2 mm) = 48 by geometry; staggered rows reach 56.
- Load check: 1,500 g / 45.93 g = 32 balls maximum, before counting the jig. A 400 g jig leaves room for 23.
A practical golf ball jig is 5 x 5 = 25 balls (1,148 g), leaving 352 g for the jig. Its plate is 5 x 43.27 + 16 + 20 = 252.4 mm square, small enough to print in one piece on a 256 mm bed. Height is fine too: a ball seated 4 mm deep in a 6 mm plate tops out near 44.7 mm, under the 60 mm camera limit.
The print area on a ball is small. Applying eufyMake’s 2 mm height-variation figure to the printed zone, the cap within 2 mm of the top of a 42.67 mm sphere is about 18 mm across (2 x the square root of (2 x 21.3 x 2 - 4)). eufyMake also notes that the printhead-to-surface distance is the biggest factor in sharpness, so keep logos inside roughly that circle. Preset: eufyMake E1 golf ball jig.
| Blank | Grid | Staggered | Practical limit | |
|---|---|---|---|---|
| 4 in square coaster | 102.2 mm | 6 (9 at 7 mm margin) | n/a | Check weight |
| 2 in round keychain | 51.4 mm | 35 | 40 | Bed area |
| Golf ball | 43.27 mm | 48 | 56 | Load: 32 max before jig; 25 practical |
3D printing an E1 jig in sections
A 330 x 420 mm plate is larger than common FDM beds. The Bambu Lab A1 builds 256 x 256 mm and the Original Prusa MK4S 250 x 210 mm. Three ways to handle it:
- Trim the plate to the pockets. The jig does not need to cover the whole bed, only the pockets plus margin, as long as it registers to a fixed corner. The 6-coaster layout’s footprint is 2 x 102.2 + 4 + 20 = 228.4 mm by 3 x 102.2 + 8 + 20 = 334.6 mm. Split once through the web between rows 1 and 2 and you get two pieces, 228.4 x 114.2 mm and 228.4 x 220.4 mm, both within a 256 mm bed.
- Split a full plate 2 x 2 along webs. For the 35-keychain grid, the web centerlines nearest the middle sit at 137.3 or 192.7 mm across and 182.3 or 237.7 mm along the length, so a 2 x 2 split gives tiles no larger than 192.7 x 237.7 mm. Cutting through a web rather than a pocket keeps every pocket wall intact.
- Use more, smaller tiles on smaller beds. On a 250 x 210 mm bed, a 165 x 210 mm quarter leaves no margin, so a 2 x 3 split (about 165 x 140 mm tiles) is safer.
Grid layouts split cleanly because there is a straight gap between rows. Staggered rows interlock (the row spacing is smaller than the pocket diameter), so there is no straight seam; if you must split a staggered plate, use a stepped seam that follows the webs, or choose the grid layout. Cut the STL along the chosen web in your slicer’s cut tool or in CAD.
Registration corner and magnets
Sections only work if they go back to the same place every run:
- Registration corner. Make an L-shaped stop at the plate origin (the corner the generator marks) and push every tile against it and against each other. The same corner becomes your zero point for Zero-Point Alignment or for the alignment template.
- Magnets. If you hold tiles with magnets, eufyMake’s warning applies: a magnet seated at an angle lifts one side and skews the height reading.
- Height check. After assembling the tiles, run Assisted Snapshot on the highest blank and confirm all blank tops read the same.
Pocket depth should be slightly less than the blank thickness so the print surface stands above the jig and nothing on the jig becomes the highest point.
Build your E1 jig
Enter the blank size, set clearance, spacing and margin in the jig generator, select the eufyMake E1 preset, and compare grid against staggered and rotated layouts. Download the 3MF or STL to print the jig, plus the alignment template and CSV of pocket centers for variable data. Related guides: UV printer jigs, jig clearance and tolerance, best material for jigs and alignment templates. Other machines and blanks are in the full combination index, and common blank dimensions are in the blank size reference. For a quick start, open Pocketplate with the E1 preset and a 2 in keychain, then adjust from there.
